SPSS for the Classroom: the Basics
Those who plan on doing more involved research projects using SPSS should follow up this brief intro with program spss in-depth training. The good news for beginners is that you can accomplish most basic data analysis through menus and dialog boxes without having to actually learn the SPSS language. Menus and dialog boxes are useful because they give you visual reminders of most of your options with each step of your analysis.
However, some tasks cannot be accomplished from the menus, and others are more quickly carried out by typing program spss few key words than by working through a long series of menus and dialogs. As a beginner, it will be strategic to learn a bit of both SPSS programming and the menus. Program spss the long run, you will want to learn to just work directly in the programming language, because this is how you document your work, and good documentation is key to both trouble-shooting and replicating complicated projects.
For now, we assume you are just carrying out very program spss tasks. When SPSS is first started you are presented with a dialog box asking you to open a file. Pick a recently opened file or pick "Open another file" from the list on the left.
SPSS Statistics has three main windows, plus a menu bar at the top. These allow you to 1 see your data, 2 see your statistical output, and 3 see any programming commands you have written. Each window corresponds to a separate type of SPSS file. The Data Editor lets you see and manipulate your data. You will always have at least one Data Editor open even if you program spss not yet opened a data set.
When you open an SPSS data file, what you see program spss a program spss copy of your data. Program spss you make to your data are not permanent until you save them click File - Save or Save As.
Data files are saved with a file type of. To open a different data set, click File - Open - Data. SPSS lets you have many data sets open simultaneously, and the data set that you are currently working with, the active data set, is always marked with a tiny red "plus" sign on the title bar.
In order to avoid confusion program spss is usually a good strategy to close out any Data Editors you're done using. As program spss ask SPSS to carry out various computations and other tasks, the results can show up in a variety program spss places. New data values will show up in the Data Editor. Statistical results will show up in the Output Viewer. The Output Viewer shows you tables of statistical output and any graphs you create. By default it also show you the programming language for the commands that you issued called syntax in SPSS jargonand most error messages will also appear here.
The Output Viewer also allows you to edit and print your results. As with Data Editors, it is possible to open more than one Output Viewer to look at more than one output file. The active Viewer, marked with a tiny blue plus sign, will receive the results of any commands that you issue. If program spss close all blizaro strange doorways firefox Output Viewers and then issue a new command, a fresh Output Viewer is started.
If you are also using the menus and dialog boxes, the Paste button automatically writes the syntax for the command you program spss specified into the active Syntax Editor.
These files are saved as plain text and almost any text editor can open them, but with a file extension of. As with the other types of windows, you can have more than one Syntax Editor open and the active window is marked with a tiny orange plus sign.
When you paste syntax from dialog boxes, it goes to the active Syntax Editor. If you close out all your Syntax Program spss and then paste a command, a fresh Syntax Editor is opened. Unless you command SPSS to do something, it just sits there looking at you. In general commands may be issued either through menus and dialog boxes that invoke the programming language behind the scenes, program spss by typing the programming language in a Syntax Editor and running the commands.
Although each dialog box is unique, they have many common features. A fairly typical example is program spss dialog box program spss producing frequency tables tables with program spss and percents.
To bring up this dialog box from the menus, click on Analyze - Descriptive Statistics - Frequencies. On the left is program spss variable selection list with all of the variables in your data set. If your variables have variable labels, what you see is the beginning of the variable label. To see the full label as well program spss the variable name [in square brackets], hold your cursor over the label beginning.
Select the variables you want to analyze by clicking on them you may have to scroll through program spss list. Then click the arrow button to the right of the program spss list, and the variables are moved to the analysis list on the right. If you change your mind about a variable, you can select it in the list on the right and then click the arrow button to move it back out of the analysis list. On the far right of reneilwe matla mp3 song dialog are several buttons that lead to further dialog boxes with soft bandanas for the frequencies command.
If you return to a dialog box you will find it opens with all the specifications you last used. This can be handy if you are trying a number of variations on your analysis, or if you are debugging something. If you'd prefer to start fresh you can click the Reset button. The main use of the Data Editor is to show you a portion of program spss data values you are working with.
It can also be used to redefine the characteristics of variables change the type, add labels, program spss missing values, etc. The Data Editor gives you two views of your data set: In the Data View, the data are laid out in the standard rectangular format for statistical software. Each row represents a unit of observation, sometimes also referred to as a record or in SPSS as a case. The case observation number in the leftmost column is assigned automatically and is not saved as data. Each column represents a variable.
All of the data in a column must be of the same typeeither numeric or string also called character. Program spss data cell holds a data value. If data are missing, they are displayed as a period ". Data values may be displayed as either the actual value or as a formatted value.
Formats can also take the form program spss value labels, for instance, data recorded as 1's and 2's might be labeled as "Male" and "Female. In particular, when you set up a command that requires you to specify one or more data values, you use values and not formatted values. You can switch the Data View between formatted and unformatted data by clicking on the Value Labels button on the Toolbar, the fourth button program spss the right when in the Data View.
With value labels on you can also see the program spss values for a given variable by clicking on a cell and then looking at the bar just above the data. The box to the left indicates the observation number and variable selected, e. Data values can be edited or added by typing them directly into the Data View.
To enter data, type in the actual data value. However, aside from very small data sets for class exercises, you should almost never need to do this. In the Variable View you can see and edit the program spss that defines each variable sometimes called meta-data in your data set: The program spss attribute of each variable is its Name. The variable name is how the data column is identified in the programming language, and in order for the programming language to work gracefully variable names have to abide by certain restrictions: Capitalization is ignored.
Variable names may be up to 64 characters long. Other restrictions may apply - no coupons please. Variable names may be added or changed simply by typing them in. The basic variable types are either numeric or string. However, just to make things confusing, SPSS allows you to select among several different standard formats for displaying numeric data e. You set the variable type by clicking in trace adkins honky tonk badonkadonk karaoke s column, then clicking on the gray button that appears and working in a dialog box.
The Label attribute allows you to give each variable a longer description that is displayed in place of the variable name, analogous to value labels for data values. Both variable labels and value labels are useful for giving you more intelligible output. The Values attribute allows you to create a list of value labels. Often several variables will share a common set of program spss labels, and in this window you can copy and paste value program spss sets.
Variable labels are set by simply typing them in, value labels work through a dialog box. The Missing attribute is a place for you to designate certain data values that you want SPSS to ignore when it calculates statistics. For instance, in survey data it is common practice program spss record a data value of 8 when a respondent says "I don't know" in response to a question, and you can have SPSS treat the 8's in a variable as if they were missing data.
The other attributes, WidthDecimalsColumnsAlignMeasureprogram spss Roleare minor settings related to data display. Although Measure level of measurement is statistically a very important concept, it has little meaning program spss the SPSS software. The Output Viewer collects your statistical tables and graphs, and gives you the opportunity to edit them before program spss save or print them.
The Output Viewer program spss divided into two main sections, an outline pane on the left, and a tables pane on the right. When you print your output, it is the tables pane that is printed. When SPSS creates output tables, syntax, error messages, etc. Individual objects may be opened and edited, deleted, hidden, rearranged, or printed.
To select an object sanam teri kasam movie songs ming video work with, you can either click on it in the tables pane, or click on the corresponding entry in the outline pane. A red arrow appears next to the object in both panes. To edit objectsdouble-click on them in the tables pane. Depending on whether you are trying to edit a simple object like a program spss which is just a box with some text in itor something more complicated like a table or a graph, you may be able to simply change the object in the Output Viewer, or another window may open.
Except for editing the look of graphs, it will often be easier to edit your output by exporting it to Microsoft Word first, but in principle you can change anything you can see in your output, down to deleting columns and changing numbers.
But if your intent is to fake your results, you should attend our Simulations workshop for better methods of doing this. To delete objectsselect them in either pane and use the Delete key.
